Collection Method:clinical testing

The c.745G>T (p.V249F) alteration is located in exon 5 (coding exon 4) of the ETV3 gene. This alteration results from a G to T substitution at nucleotide position 745, causing the valine (V) at amino acid position 249 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
